It’s not that the dialogue doesn’t sound right, it’s that the dialogue is disconnected from the game.

A great example was someone did this with Skyrim a while back. In the dialogue they convinced the NPC to join their party. But there isn’t any code logic to allow that, so the NPC is talking like they joined the person’s party, but the gameplay itself doesn’t support it.

Now for animal crossing you could make it work a bit easier cause the character can’t directly interact with the NPCs, but then again it also makes the endless dialogue less impactful.
